See introduction for complete context.
Part 1 - Here is an FCC ID, Q87-WRT54GV81, what is the frequency in MHz for Channel 6 for that device? Submit the answer to port 3895.

Simple Google Search reveals that we can look up the FCC ID [here](https://fccid.io/). [This](https://fccid.io/Q87-WRT54GV81) is what we're looking for.
Checking the RF Exposure Info and doing Ctrl+F for "channel", I quickly found that the frequency was 2437 MHz. Now, don't spend 20 minutes wondering why the submission wasn't working like I did, and check the discord to realize that you have to check the hint to get a valid submission.
```
printf '2437\n\0' | nc 35.225.17.48 3895
```
And now we get the flag:
{FCC_ID_Recon}
